Hopper conducted a study that looks at the range of prices people pay for airfare by analyzing flight search results between major U.S. cities.

They found that economy seats on a flight from Los Angeles to Las Vegas can cost anywhere from $200 to a whopping $1,600. The study shows that while airfares can vary tremendously on most airlines, Spirit Airlines and Virgin have the most consistent ticket prices for this flight route.

Hopper also looked at other routes and concluded that flights between Chicago O'Hare and John F. Kennedy airports have the most equal ticket pricing.

In order to avoid paying way too much for your airline ticket, Hopper suggests buying your ticket at least 30 days in advance.
